E-STOP relays, safety gate monitors

Transcription

1 Unit features Positive-guided relay outputs: 2 safety contacts (/O), instantaneous Connection options for: E-STOP pushbutton Reset button LED indicator for: Switch status channel 1/2 Supply voltage See order reference for unit types The circuit is redundant with built-in self-monitoring. The safety function remains effective in the case of a component failure. The correct opening and closing of the safety function relays is tested automatically in each on-off cycle. Safety relay for monitoring E-STOP pushbuttons. Approvals Unit description The safety relay meets the requirements of E and IEC and may be used in applications with E-STOP pushbuttons The safety relay is not suitable for noncontact barriers because a dynamic start is not possible the unit can be started during the delay-on de-energisation time. Safety features The relay conforms to the following safety criteria: Block diagram A2 Y1 Y ~ ( )* = Input Reset/ Start K1 Power K2 ( )* *Only when U B = VAC Galvanic isolation only when U B = VAC

2 Function description Single-channel operation: no redundancy in the input circuit, earth faults in the reset and input circuit are detected. Timing diagram Automatic start: Unit is active once the input circuit has been closed. Manual reset: Unit is active once the input circuit is closed and then the reset circuit is closed. Increase in the number of available contacts by connecting contact expander modules or external contactors/relays. 1 2 a b Reset/Start Power/Input Output safe t1 t2 t1 t2 t1 t2 t1 t2 Key Power: Supply voltage Reset/start: Reset circuit Y1-Y2 Input: Input circuits Output safe: Safety contacts 13-14, : Automatic reset : Manual reset a: Input circuit closes before reset circuit b: Reset circuit closes before input circuit t 1 : Switch-on delay t 2 : Delay-on de-energisation Wiring Please note: Information given in the Technical details must be followed. Outputs 13-14, are safety contacts. To prevent contact welding, a fuse should be connected before the output contacts (see technical details). Calculation of the max. cable runs l max in the input circuit: I max = R lmax R l / km R lmax = max. overall cable resistance (see technical details) R l /km = cable resistance/km Use copper wire that can withstand 60/75 C. Sufficient fuse protection must be provided on all output contacts with capacitive and inductive loads. AC: The cable runs depend on the cable capacitance. Loop circuit, 1 phase: max. l r = 1 km Stub circuit: Cable capacitance C L and therefore the cable runs l s are dependent on the supply voltage U B Cable capacitance C L depends on the supply voltage U B U B [V] C L [nf] Loop circuit Stub circuit Cable runs UB lr A2 AC UB ls A2 AC -2

Use the notch on the rear of the unit to attach it to a DI rail. Ensure the unit is mounted securely on a vertical DI rail (35 mm) by using a fixing element (e.g. retaining bracket or an end angle). 121 (4.8") 75 (2.95") 87 (3.42") 22,5 (0,89") -4
